Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

Abstract

Boron phenylalanine is one of the lead drug candidates in the field of Boron Neutron Capture Therapy. Its inherent low toxicity allows large doses to be administered, but this makes it important to identify, rationalise and quantify impurities. Here we report a chromatographic assay method, the conditions under which the parent compound is unstable, and the suggested degradation mechanisms.
